TILE.

SPECIFICATION forming part of Letters Patent No. 627,327, dated June 20,1899.

Application filed April Z4, 1 8 9 9 To all whom it may concern.-

Be it known that I, GEORGE W. OROWE, a citizen of the United States,residing at Anderson, in the county of Madison and State of Indiana,have invented certain new and useful Improvements in Tiles, of which thefollowing is a specification.

The object of my said invention is to produce a tile which in being setwill become very securely locked or attached to the bed of mortar uponwhich it is placed. It is especially designed for that variety of tileswhich are used on walls, as the walls of bathrooms and the like. Saidinvention will be first fully described and the novel features thereofthen pointed out in the claims.

Referring to the accompanying drawings, which are made a part hereof andon which similar reference characters indicate similar parts, Figure 1is a perspective view showing the under side of such a tile embodying mypresent invention; Fig. 2, a plan view of the under side of such a tile,on an enlarged scale, substantially full size, as ordinarily made; Fig.3, a longitudinal sectional view as seen from the dotted line 3 3 inFig. 2, and Fig. 4 an end elevation of the same as seen from v thedotted line 4 4t alongside Fig. 2.

The distinctive features of this tile are the tapered and nnderhung ordovetail-shaped recesses 1 and 2. These recesses, as clearly shown inthe drawings, are of such a form as to be readily withdrawn endwise offthe face of the mold part by which these surfaces are formed, while theyare adapted to lock firmly onto the mortar in which they are embedded.The recess 1, as plainly shown in the drawings, tapers down also on anangle with the faceof the tile, being deepest at its narrowest end andgradually diminishing to nothing at its widest end. The edges, however,overhang the space, both across the narrowest end and along the sides.The recess 2 is Serial No. 714,306. (No model.)

bottom is parallel with the surface of the tile, and its widest end,instead of terminating on the flat surface, terminates at the end,

as plainly shown in the drawings. Like the recess 1 its edges at thenarrow end and along the sides overhang, so that the recess is widest atthe bottom.

The remaining portion of the under surface of the tile is substantiallycovered with grooves g, which aid,when forced against and embedded insoft mortar, in securing the tile rigidly and strongly in place.

Having thus fully described my said invention, what I claim as new, anddesire to secure by Letters Patent, is

1. A tile having upon its under surface the tapered recesses 1 and 2which are narrowest at the closed ends and widest at the open ends withthe edgessurrounding the narrow ends and sides formed overhanging, saidrecesses being widest at the bottom while adapted to be easily removedfrom the mold by reason of their tapered form, substantially as shownand described.

2. As a new article of manufacture, a tile having the recesses 1 and 2,said recess 1 being deep at the narrow end and tapering back thenceuntil it wholly disappears at its wide end with those edges which boundits narrow end and sides formed overhanging making the same dovetailed,and the recess 2 being likewise formed narrow at its closed end and wideat its upper end with the edges corre spondingly overhanging, the saidrecess 2 being of equal depth with its wide end coin- 8o cidental withthe end of the tile, all substantially as shown and described.

In witness whereof I have hereunto set my hand and seal, at Anderson,Indiana, this 19th day of April, A. D. 1899.

GEORGE w. cnown.
